Polaris solar PV net news: the United States is currently engaged in the study of thin-film solar company first solar (First Solar) and Sun company. According to Zhang Liang studied at Iowa State University solar energy Dr, first solar to produce thin-film solar cells based in Sun City company to produce and sell its own homegrown. He says prospects emerging thin-film solar cells is good, but needed to solve the problem.

At present, the United States apart from first solar, other solar companies to survive in the commercial market is not easy. Thin-film solar cells for energy companies to profitability is no small challenge. The reason, as one of the new energy of the solar energy in the United States is not widely used, is not enough demand. According to the United States Federal Government data show that in 2014, renewable energy provides 13% of United States power. Among them, 50% of electricity comes from hydropower, 30% from wind power, only 3% from solar power. In addition, less raw material of the thin-film solar cells, producing a smaller number. Some of the thin-film solar cells, such as the Copper-Indium-Gallium-selenium solar batteries, cadmium telluride thin-film solar cell materials are raw materials, not easy to prepare too much. Part of the thin-film solar cells are still in experimental stages of development, there are still many sceptical researchers use life expectancy.
“Entered its third generation solar cells!” Germany financial network reported that following the first generation of monocrystalline silicon solar cell, after the second generation of polycrystalline silicon solar cells, the third generation of thin-film solar cells are gradually becoming the mainstream of Europe’s solar cell production. The EU currently has 200 solar manufacturers to produce thin-film solar cells, including, in particular, in Germany most manufacturers.
Headquartered in Germany Munich weixite technology consulting firm survey, thin-film solar cells for nearly 10 years in the Germany development Germany solar cells increased from 5% to 25%. Germany solar cells 40% exported, thin-film solar cells account for a considerable proportion.
In recent years, Germany’s solar industry started a new round of reshuffle, crystalline silicon solar companies such as Bosch and Siemens stop its solar business, but high-tech equipment manufacturer Germany Manz group new breakthrough in the field of thin-film solar. The Group has previously announced that has copper, indium, gallium and selenium (CIGS) thin-film solar cell experiment conversion rate from the previous 20.8% to 21.7% over polysilicon experiment conversion rate 1.3%.
For thin film solar cell efficiency, from Germany, and Switzerland, and France, and Italy, and Belgium, and Luxembourg, 8 European countries 11 research team formed a Research Alliance last year and declared a State of “Sharc25” program, aimed at CIGS thin-film solar cell conversion efficiency from the current 21.7% to 25%. They hope that the next few years, solar cells can be used in wearable electronics and other small devices, but the ultimate goal is for buildings and public utilities such as solar farms for large-scale power generation. “If this goal can be achieved, performance can be a qualitative leap in the European solar cell will maintain dominance in the global market. “Germany solar cells also quoted experts as saying that the widespread use of thin-film solar cells, will contribute to the rapid decline in the cost of solar power generation in the next 15 years, which is expected to be the cheapest source of energy.
However, if you want to make thin-film solar energy really come into people’s lives, increase people’s awareness, also needs creative and useful products. In 2015, the Netherlands Holst Centre (HolstCenter) and a Netherlands fashion designer launched a solar-shirt. 120 pieces of thin-film solar cells sewn into clothing, one wears it in the Sun to generate electricity, and can be processed within a few hours for a iPhone cell phone is fully charged, camera, MP3 player, GPS and other devices that use USB interface to provide electricity or electricity storage for night use. Moreover, this product also can be cleaned like ordinary clothes.
According to the Japan economic news said Tokyo called “system TOOKYSU” company has developed a thin solar charger, 90 minutes to finish charging the iPhone price to 5600 yen ($ 361 million). Japan’s Mitsubishi Chemical, announced last year, and the United States jointly develop organic thin-film solar cells, towards 2016 within the listing. This product is translucent film, can be posted on the Windows of the Office building, used the term at least 10 price is about 10,000 to 20,000 yen per square meter, the company has also tried to further reduce the price.
As early as in 2010, Japan space development agencies began to experiment, with thin-film solar cell power generation as a space power, currently known as Ikaros test of thin-film solar powered aircraft had lifted off, provide test data for the exploration of Venus. In addition, Japan is still in an experimental space solar electricity in a wireless way to Earth, currently has achieved certain results.
